After a brief halt and reset during the last few seconds of the countdown, the unmanned Starship + Super Heavy stack lifted off like nothing ever before.

But the rocket’s Super Heavy first stage booster, though it achieved a crucial manoeuvre to separate with its core Starship stage, exploded over the Gulf of Mexico shortly after detaching, a SpaceX webcast showed.

During the livestream, SpaceX explained that the big objective of the day was to get past stage separation, which is the part of the launch that involves the Super Heavy booster disconnecting from the ship.

SpaceX intends to make both stages of the Super Heavy reusable, which will make missions using Starship/Super Heavy less expensive and more sustainable.

Starship is actually two vehicles — the Super Heavy rocket booster and the Starship spacecraft.

The method was used to separate the Starship spacecraft and Super Heavy rocket after liftoff.

The Super Heavy booster will likely make a hard splashdown in the Gulf of Mexico about eight minutes after liftoff.
